PAPER-CLAIVI P.

SPECIFICATION forming part of Letters Patent No. 448,822, dated March 2i, 1891.

Application niet May 14., 1889.

To @ZZ whom, it may concern:

Be it known that I, JOSEPH B. MCGIRE, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Paper-Clamps, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The object of my invention is to provide a new and useful article ofmanufacture, which Iihave illustrated in the accompanying drawings, inwhich- Figure 1 is a perspective of the paper-fastener attached to thetable. Fig. 2 is a perspective of the fastener detached. Fig. 3 is aside View. Fig. 4 is a side view showing method of operation. Fig. 5 isa view showing it adapted for artists use. Fig. 6 is a perspective ofthe clamp made of iiat material. Fig. 7 is a side view showing itadapted for decoration. Fig. S is a modification made of hard wood. Fig.9 is a view of fastening attached to a drawing-board. Fig. 10 is aviewof fastening with protectors on board. Fig. 11 is a top view showing howused by draftsmen. Fig. 12 is a detached view of modification. Figs. 13to 19, inclusive, show different views of my invention in different andvarious forms.

Like letters indicate like parts throughout the drawings.

A represents in general the clips or fastenings which I propose to puton an ordinary drawing-board.

B represents the roughened or toothed surface ofthe fastener.

C is the part that is pressed upward to get the paper under, as will bedescribed farther on.

D is the part which holds the paper in place.

F. represents the board in general.

F is the paper that is to be held in place.

To overcome some of the trouble that occurs very often with draftsmenand artists, as well as architects and others, in keeping their paper inplace, it has been very troublesome to have the drawing, design, ttc.,-inished Without its being punched full of holes, which is the case whenthey use the thumb-tacks, which also get lost and are very troublesometo keep, whereas with the fastening of this character it can be held inposition and also always on the board. When used by draftssera No.310,697. (No moda men, it not only holds the paper on the board, butitis plumb and saves the time of plumbing it, as is done when tacks areused. These fastenings, when placed on the board, can be placed andadjusted with great rapidity and made to fit different sizes of boards.In practice I- propose to have the board F. nicked the depth of thefastener, (when used by draftsmem) so that when in place and the paperunder, the square can ride over it Without any hinderanee. Thus when onthe board and desiring to put paper under, all that is necessary is topress on the flat portion c with the finger, as is shown in Fig. 4, andit rises sufficient to admit the paper. While thus open, it will bereadily seen that the paper can be pushed under with ease, and byrelaXing the hold it Will fall back in place and hold the paper that isunder secure and prevent it from slipping. On this end D or on thepaper-gripping end can be teeth-such as is shown at B--for the purposeof insuring against slipping after once let down into position.

-What has caused draftsmen, architects, dto., trouble is that their workwas all full of holes from the tacks, and if their drawingboard was notin very good condition the paper would become loose and slip, causingdelay to the one who was using the board. The fastenings are made, aswill be seen by Fig. 2, of one continuous piece of bronze wire, which isround in cross-section, or of any other suitable material, and bent inthe angles thus shown for the purposes of getting the spring to hold thepaper to the board. Then the finger-piece is put on in a suitable way topress the finger against for the admittance of paper. With both edgesor'rather with both faces of the fastening thus toothed it Will be seenthat it Would not slip off very easily. The wire-after being cut thedesired length is then flattened at both ends and made rough or toothedand then bent in the desired shape.

Referring to Fig. 7,it will be seen'that it can be used forotherpurposes than has been explained. This fastening is made thesame as thatshown in Fig. 2 and is also round in cross-section. W'hen stores displaycards, they have some little trouble in keeping them in place and alsoto keep them from becoming full of holes by using pins to fasten IOO eMesse them. This can be accomplished by using a rack with a number ofthese fastenings on, and then placed in the window or show-case and bedisplayed, as is done new. This fastening can be used by others fordisplaying purposes, it being cheap and handy and easy to manipulate.

Referring to Fig. 8, it will be seen that the meansforobtainingthespringisalittle different, it being in this case by awire being wound around three or four times in a circle, as shown at J,and then on one end making a loop, as shown at h, and the other partsare about the same as those in Figs. 2, 3, 4, ttc. These attachments orpaper-fasteners can be used on the board for tiling unanswered letters,and they can be taken olf with as much ease as when used by draftsmenand be less complicated than the ones now in use, as there is nothing toget out of order. When this style is used by architects and designers,it would be well to put a small strip of wood on the ends of the boardfor the purpose of not wearing the spring, as I have shown at G. Thus itwill be seen that the spring will never come in contact with the tableor desk and will hold the paper that is under the fasteningsecme5butthisstripGisimrnaterialinthat respect, as it would require agreat pressure to release the paper that is under the fasteningthat isto say, with the elbow, which is more or less on the drawing-board whenin use. lVhen desired to release the paper, it can be done very easy bythe proper means, as described.

Referring` to Figs. 11 and 12, in this modification I get the springfrom bending' the piece of metal atj, and at the end D screw it to thebottom of the board. By doing so it brings the surface b to the bottomof the board and brings the surface I) also tight against thetop, underwhich the paperis put. \Vhen thus applied, it will be seen that thesquare II can be slid over much faster without interruption, as has beensaid before. I have found that it is also agood and safe way to put thepaper-fasteners A on the top of the board, as shown in Fig. 5. Then theoperator has a plain uninterrupted surface to work on. Of course thesepage1-'fasteners will be made separate and distinct from the boards tobe sold to those who would want to use them for other purposes and beplaced in any way that they desired.

Fig. 13 is a modification made in two pieces, as shown at C and b. Boththese pieces are made the same shape as those already referred to; butat the end c they are provided with a hole to admit the end of the upperportion A', which has at its lower end a small piece to extend throughthe spring (j, and then can be fastened in any suitable way to the smallpiece c', which holds the piece A from coming out of the hole in whichit is placed. The end of course is made in the same way that the othersare, with the exception of a slight upward turn. This may be obviated byjust tiling the edge a little, making a round edge instead of an angle.It will be seen by Fig. 15 that the edge B of the board is uninterruptedand will permit the free use of the square, as said before.

As shown in Fig. 1G, the parts are arranged the same as Figs. 12 and 18,with the exception that this style is more adapted for letter andnewspaper files, and is operated the same as the others by pressing onthe spring C. It can, as I have shown, be provided with a small lug onthe side to accomplish the same result. I bend these fastenersdifferently at their ends to get a good grip on the article to beclamped. This can be done by a fiat portion u, turned downward andinward at a very slight angle; also, the saine result can beaccomplished, as shown in Fig. 17, with the teeth on the bottom, asshown at a2, to grip the paper. These teeth will resemble those of asaw. Thus it will be seen by Fig. 18 how the paper will be tightly heldin place and ready to be taken off at any desired time, as is done withthe files new in use.

Fig. 19 shows the use to which it can be put by using it as a newspapertile or holder, thus keeping the papers together and in good conditionuntil put away.

Of course it will be understood that many details shown and describedcan be more or less modified without departing from the essential partsof the present invention. I have shown and set forth that form ofdevices which is at present preferred, but do not wish to be limitedexactly thereto. The fastener, as shown, can be detachable, or joined inother ways. In fact, this feature is not limited to the use ofarchitects and draftsmen, as described. So, too, the fastener can bebent and the parts can be connected with thebase or board other thanshown.

From the drawings and the foregoing de script-ion it will be observed.that each of these various forms of paper clamps or holders comprises aspring arm or portion beneath and bearing against the under face ofaboard and the arm carried by the spring and having the lateralpapei'holtling arm held down on the upper face of the board by thespring to hold the paper, the spring being obtained by the portionbeneath the board.

It is evident that various changes might be resorted to in the form andarrangements of the parts described without departing from the spiritand scope of my invention. Hence IOC IIO

I do not limit myself to the precise construei tion herewith set forth.

l. A paper-holder adapted to removably fit on the edge of a base orboard, formed integral, and having a rigid vertical arm and lateralpaper-holding arm, the lower portion forming a continuation of saidvertical arm and bent to form aspring, and an arm to bear against theunder face of the base or board, substantially as and for the purposeset forth.

2. The combination, with a board, of one or more paper-holding clipsupon the edge of the same, each clip comprising a paper-holding arm onthe upper surface of the board, and a spring portion beneath and bearingagainst the under surface of the board and connected with said arm andholding the same down on the board, substantially as set forth.

3. The combination, with a board having a transverse groove in its edge,of a paper-holding clip tted on said edge and comprising a paper-holdingarm, a spring portion bearing against the under face of the board, andan arm in said groove carried by the spring portion and carrying saidarm, substantially as set forth.

4. As an article of manufacture, a paperholding eli p to fit on the edgeof a board, cornprising a spring portion bearing against the undersurface of the board and the paperholding arm carried by said springportion and held thereby, bearing down on the upper face of said board,and having its engaging surface roughened, substantially as and for thepurpose set forth.

5. As a new article of manufacture, a paperholding clip formed in onepiece and consist'- ing of a long spring-arm to bear against the undersurface of a board, and the arm extending at right angles from themovable end of said spring and having the lateral paper-holding arm atits free end, substantially as and for the purpose set forth.

6. A paper-holding clip to tit the edge of a board, substantially asdescribed, consisting of a spring-arm adapted for rigid connection Withaboard, and a paper-holding arm carried by the free end of saidspring-arm and maintaining the saine relative position thereto at alltimes, as set forth.

7. A paper-holding clip for application to the edge of a board,substantially such as herein described, coinprsinga yieldingspringarmadapted for rigid connection at one end with a board and a rigidpaper-holding arm arranged substantially parallel with the spring-armand supported by a vertical part which joins the spring-arm at its freeend, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.l
